1, no obvious relationship with cervical spondylosis, but may have some significance when considered in combination with occupation and labor intensity. 2.Age Cervical spondylosis is a common and frequent disease of middle-aged and elderly people, is currently a more consistent view. The peak of the disease is between 40 and 60 years old, and in recent years there is a trend of younger. 3.Occupation Cervical spondylosis occurs in people who work with their heads down. Such as accountants, typists, embroidery workers as the high incidence of the population. Hu Jiayan surveyed 1,064 people in a large factory and mine in 1982, and the prevalence rate was 17.19%. Danish scholars found the highest prevalence of drivers through epidemiological surveys of cervical spondylosis. 4.Trauma Among patients with cervical spondylosis, the cause of the disease varies from 10.29% to 32.6% due to trauma, and the Japanese reported that 70% of sympathetic cervical spondylosis has a history of trauma. 5, lifestyle habits ① high pillow sleep, our scholars have found that symptoms appear after 5 years of high pillow sleep. ②Heavy head, the prevalence of cervical spondylosis in Korean women is four times higher than that in Han Chinese women. ③ alcohol consumption, Hu Jiayan investigated 1064 cases, including 359 cases of alcohol drinkers, suggesting that drinkers are more likely to suffer from cervical spondylosis. 6.Anatomical variants such as fusion of cervical 2 and cervical 3 vertebrae, vertebral arch root and vertebral plate bone protrusion, cervical ribs, hypertrophy of the transverse process of the 7th cervical vertebra, cervical cryptorchidism, and skull base depression. 7.Climate The onset of cervical spondylosis is related to natural factors such as high altitude, thin air, low atmospheric pressure, low oxygen partial pressure, cold, large temperature difference between day and night, and strong ultraviolet rays. Cervical vertigo is closely related to the poor stability of autonomic function and cervical sympathetic nerve dysfunction in elderly people in highland areas, which leads to cervical artery spasm. 8, genetic factors Some scholars believe that the occurrence of cervical spondylosis may be related to genetics.
